I should warn you: I’ve submitted DNA samples to both the National Genographic project and to 23andMe. As we’ve just learned, that means the police can use that data to connect DNA samples collected at crime scenes to my relatives, which means they have a lead to you even if you haven’t given a DNA sample. Honestly, if I do have any criminals in the family, I would kind of hope they could stop you with that information.
However, I don’t remember giving the police permission to use my genetic information — it was probably buried in tiny print somewhere in an agreement I signed. That’s a bit troubling. OK, a lot troubling. Now I’m wondering who else has access. So, if there’s a disease-associated trait somewhere in my background, are the insurance companies going to knock on the door of my second cousins somewhere and announce that they now have grounds to suspect that there is a medical problem lurking in their genome, and they’d better cough up some increased rates?
